DEVICE FOR ATTACHING HANDLES TO CARPET-SWEEPER BAILS.

SPECIFICATION forming part of Letters Patent No. 785,027, dated March14, 1905.

Application tiled April 1, 1902. Serial No. 100,964.

T0 all whom it may concern:

vBeit known that I,DELL F. STARKWEATHER, a citizen of the United States,residing at Grand Rapids, in the county of Kent and State of Michigan,have invented new and useful Improvements in Devices for AttachingHandles to Carpet-Sweeper Bails, of which the following is aspecification.

This invention relates to a certain new and useful improvement in themanner of attaching handles to sockets; and it is more particularlyadapted for the attachment or connecting of a wooden handle to the bailof a carpet-sweeper.

The objects of the invention are to simplify the construction of theattaching device and also to provide a durable covering or casing forthe wooden portion of the handle and to prevent the handle from workingloose in the socket, the invention itself consisting in providing ametallic strip of suitable material adapted to surround and snugly fitthe screwthreaded portion of the handle and to form a covering andprotection for the screw-threaded end of the handle and to engagetherewith in such a manner that it will not become Iemoved therefrom.These yobjects are accomplished by means of the mechanism illustrated inthe accompanying drawings, in which- Figure 1 shows a perspective Viewof the portion of a wooden handle with the metallic strip secured to thescrew-threaded portion of the handle. Fig. 2 shows the form of the stripwhen it is bent up ready to apply to the handle and before thescrew-threads are formed thereon, a portion of the strip being cut awayfor the purpose of more fully illustrating its structure. Fig. 3 showsan end view of a handle with the metallic covering applied thereto, theend of the handle showing the modified form of slot. Fig. 4 shows a Bshows the metallic inclosure after the same has been applied to thescrew-threaded portion of the handle and pressed into engagement withthe threaded portion of said handle. In constructing and applying thisdevice the strip is bent in the .form of a shell provided with a slot,(shown by D.) The slot D may extend entirely through the handle, asshown in Fig. 1, or may extend partially through. as shown in Fig. 3.'The metallic shell is first bent into the form shown in Fig. 2, theedges C being bent inwardly,

so as to extend toward the center of the cylinder or circle. The shellis then applied to the threaded end of the handle, the two edges C beinginserted in the slot D. When the pressure is applied in order to producethe screw-thread on the shell and to cause the same to fit into andengage with the screwthreads on the handle, the bent portion C will bedriven into the slot D and the cylindrical portion of the shellv pressedinto the threaded portion of the handle, so as to make a complete andperfect engagement in the form shown in Fig. 1. A handle constructed inthis manner would readily engage with the screw-threaded socket, and asthe handle is turned so as to cause the screw-threads of the handle toengage with the screw-threads of the socket there will be a tendency tostill further clasp the shell B upon the handle.

Having thus describedy my invention, what I claim to have invented, anddesire to secure by Letters Patent, is-

A carpet-sweeper handle having a tapering screw-threaded end providedwith a slot and a metallic reinforcement forming a permanent l part ofthe handle, said reinforcement conl sisting of a strip of suitablematerial surl rounding and Conforming in Contour to said screw-threadedend and having the ends thereof extending` in said slot and the abuttingportions thereof iiush.

In testimony whereof I have hereunto set my hand in presence of twosubscribing Wltmesses.
